Question

我正在尝试更改此查询，以便按日期正确排序。

此行有效，但未按顺序排列所有日期。按年份排序，而不是按日期和月份排序。

$query = mysql_query
("SELECT `date` FROM `table` WHERE `day` LIKE '%$row->period$row->friday%' AND date != '' ORDER BY `date` DESC LIMIT 1");
    while($row2 = mysql_fetch_object($query)){
        echo $row->date;

我创建了这个，但回声保持空白。我做错了什么？

$query = mysql_query
("SELECT DATE_FORMAT(date, '%d-%m-%Y') as `date2` FROM `table` WHERE `day` LIKE '%$row->period$row->friday%' AND date != '' ORDER BY `date` ASC LIMIT 1");
while($row = mysql_fetch_object($query)){
    echo $row->date2;

Answer 1

语法错误。

      SELECT `date` FROM `table`
      WHERE `day` LIKE '%".$row->period."%'
      OR day like '%".$row->period."%' AND date != '' ORDER BY `date` DESC LIMIT 1")

如何使用此查询按日期排序
